The earth cannot rotate on a different axis. The earth rotates on its own axis to change the
axis path would require a big change in an angular momentum which is not possible. The
earth rotates on its own imaginary line passing from North Pole to South Pole
known as axis of the earth.
These happens once in 24 hours .The north poles is
the point where the earth’s axis of rotation meets surface and its distinct
from earths north magnetic pole .Its south poles is the point where the earth’s
axis of rotation intersects its surface in the Antarctica.
